I spoke with a lab supervisor at Bioreference regarding the eia v lcms testosterone test and he said that if levels are not low that eia is fine to use and no need for lcms.
And I do agree that sensitive test is subject to lab error way more so than eia method.
May be able to say the same with the e2 test.
Here’s a test
This from Bioreference @highpull so would I say I crashed with e2 lcms less then 5 but eia has 23? Also I believe when I spoke with lab supervisor he says that estradiol was all estrogens and the e2 one was just the e2???
